Hey all! My son (18) just bought a 1987 GL 2+2 Non-turbo manual. We have been working on some odds and ends and I found a couple of connectors in the engine bay unplugged. Can anyone tell me what these are and where they connect (if they do)?

The first one is on the driver's side next to the brake booster and master cylinder.
The second one is right up against the firewall behind the intake and next to the windshield wiper motor.
Any thoughts? Thanks!
